[streaming] DVBlast - DVB-S2 success?

[Wilb]

Hi,

I originally posted the to the VLC forums but was advised to post it to the
DVBlast list. As the streaming@ one is the one suggested for user support I
have signed up to it and here is my issue. If you think it would be better
posted to the developers list then I will do that.

I've been trying to get DVBlast up and running so I can use it to stream
4:2:2 DVB-S2 feeds to VLC under Linux. Unfortunately I'm having no luck so
far, although I have got it picking up normal streams. Here are some
examples of commands I can use to successfully pick up some normal DVB-S
streams (motor is being manually moved before i invoke any commands):

VIVA Polska from 13e: dvblast -c dvblast.conf -f 11075000 -a 0 -n 0 -e -t 3
-v 13 -s 27500000
BBC One 28.2e: dvblast -c dvblast.conf -f 10773000 -a 0 -n 0 -e -t 3 -v 18
-s 22000000
Al Jazeera 10e: dvblast -c dvblast.conf -f 11140000 -a 0 -n 0 -e -t 3 -v 18
-s 2894000

Each command would list the relevant SIDs which I could then put in my
dvblast.conf and stream through VLC.

10e has a large amount of feeds so that is the one I'm trying to focus on at
the moment. If I manually add a transponder in Kaffeine which I know has a
feed on (12677000 horizontal, S/R 6666000) and scan, it picks up a service
labeled "TV-UNIT D207 B". Unfortunately xine doesn't handle 4:2:2 streams
otherwise I would just use that for playback - instead it crashes. There
doesn't seem to be any sort of Linux based 4:2:2 playback solution other
than a combination of DVBlast & VLC.

Unfortunately if I try and hit the same frequency / symbol rate with dvblast
that with DVBlast it picks up nothing and just gives lots of the following
to the console:

debug: frontend has acquired signal
debug: frontend has acquired carrier
debug: frontend has lost carrier
debug: frontend has acquired carrier
debug: frontend has lost carrier
debug: frontend has acquired carrier
debug: frontend has lost carrier

I seem to recall it also did this when I tried to pick up BBC HD from 28.2e
but I'm not in a position to test that again at the moment. Adding -m qpsk
or -m psk_8 do nothing either.

Has anyone succesfully used DVBlast to pick up anything DVB-S2? For
reference I'm using a WinTV Nova HD DVB-S2 card. I've compiled the latest
v4l-dvb as well as the latest dvblast from Subversion.

Many thanks,

Wilb
